My son is 19 months old. i feel like he isn't talking a lot. he says a good amount of words, but i just feel like he's not speaking enough. what should i do?

Be patient: Be sure adults/older sibs read to him and talk to him regularly (not "baby talk") and frequently. The noise from tv does n-o-t count and should be limited. As long as he communicates his needs (here you may want to wait more for him to say need, not just point / grunt and you guess it and do it w/o him saying it) and hits his other milestones, should not be a problem. Check w/peds next visit to dr.

Get an evaluation: My general rule of thumb is that if a parent is worried, it is worth getting your child evaluated. It is good he is saying words, so he probably is hearing well. A 19 month old child should be saying around 20 words. Between 18 and 24 months of age, their vocabulary is exploding. If you are seeing that, he actually is probably ok. Still, talk to your pediatrician.

May be ok: At 19 months, most children have a vocabulary of at least 20 words but there is a lot of variation. By 2 years he should be using at least 50 words and some 2 word sentences. Talk to your son's doctor if you are worried.

If your hypothyroidism was treated & your TSH & Free T 4 were normal during the 1st 12 weeks of pregnancy, it likely did not impact fetal development. Intent to communicate, reciprocal social interaction & joint attention (pointing to share interest & following a point) & pretend play should be present.
